When installed into Heli-Coil STI tapped holes, inserts provide permanent conventional 60° internal screw threads that accommodate any standard bolt or screw.
Heli-Coil threaded inserts boast a high wearing tensile strength, low thread friction with tight tolerances, and a high surface quality as well as corrosive- and heat-resistant properties.
With Heli-Coil threads, tapped holes are strengthened and thread life is dramatically increased even after repeated assembly and disassembly. Tapped holes are easily incorporated into existing designs.
Heli-Coil offers a complete line of tooling from hand, pneumatic, and electronic installation tools to STI taps, gages, and tang break-off tools. Free running and screw lock Inserts are available in a wide choice of materials to suit specific application needs.
